Setting SPI_TRANS_FAIL_IO has no effect if the transfer completes in the
current context, as it is only handled when .transfer_one() returns > 0,
when the SPI core must wait for the SPI transfer to complete.

Do not set SPI_TRANS_FAIL_IO as we either return an error or 0, since we
do our own waiting.
